One critique I often hear from people about btc is how btc mining is unfair somehow. However we must realize that btc is a threat to the current political economic system. It would not surprise me that political decisions will be made to attack btc networks by literally buying computing power to distort btc block chains and affiliated networks. Couldn't thousands of real or virtual computers be purchased by governments to add spurious transactions to btc block chains with hacked btc clients? Therefore we could be facing a war of escalating computing power. The good news for btc is that computer mining is creating incentives for a powerful btc computing network that will make it very difficult for governments to catch up. Thoughts?
